This invention relates to improvements in window construction, and particularly in the type of window construction having upper and lower sashes sliding in parallel planes.

Still morev specifically, this invention relates to improvements in the type of window construction having upper and lower sashes sliding in parallel planes, wherein the sashes are pivoted upon riders and can be displaced angularly fromtheir planes of sliding. A The primary object of this invention is to the riders of the partially unbalanced sash 7 weights. Another object of this invention is to provide window construction of the aforesaid character, wherein the sashes can be entirely detached from their riders, so permitting the repairing of the sashes, the cleaning of the outside faces of the window panes, the installing of outside screens, and the passing oflarge objects such as furniture through the window tobe accomplished with ease. Another object pf this invention is to pro videwindow construction of the aforesaid character, wherein both sashes however riders in q vation or pbsition by angular displacements greatly displaced angularly from their planes of sliding are never in interference with outside screens or shutters. Another object of this invention is to provide window construction of the aforesaid character which is adequately waterproof, draftproof and burglarproof. Another object of this invention is to provid riders and means for locking these heir stile grooves at any given eleof the sashes pivoted upon these ride-rs, adaptableto the present type of window frames and sashes, so that the installation of pivoted detachable sashes 'in the window frames .of existing houses can be effected inexpensively and in a simple manner by making slight alterations in the construction of the window frames and of the'sashes now in use.

The realization of these and of other objects by this invention can best be realized and appreciated by an examination of the following description and the accompanying drawingswherein a particular embodiment of this invention is described and illustrated. The scope of the invention is defined in the appended claims.

Referring now to the drawings in which similar numerals are used to designate corresponding parts throughout the several views and primed numerals are used to designate similar parts generally not shown in the views:

Figure -1 is a view in perspective of the improved window construction showing the lower sash displaced angularly from its plane of sliding to an extent greater than ninety degrees, and the upper sash completely detached from its riders.

Figure 2 is a view in cross section of the closed window along the line 22 of Figure 1, showingthe left-hand portion of the window frame and portions of the sashes and of their riders in their planes of sliding.

The view of the portion of the upper sash and of its rider is in cross section, while that of the portion of the lower sash and of its rider is an external one.

Figure 3 is a view in perspective of the right-hand lower corner of the lower sash showing the design of the pivot bearing plate to which reference will lateribe made.

Figure 4 is a side elevational view partly sectional, and also partly cross sectional of the left rider of the lower sash, in which are shown the pivot, the mechanism for locking the rider in its stile groove, together with the notched structure of the stile. groove with which the locking mechanism engages, and the slot which acts as a catch for the left-hand spring bolt upon the top of the lower sash. This spring bolt and catch together with the pivot and pivot bearing serve to hold the sash and its rider united in their plane of sliding.

In'the drawings, 1 designates the window frame of the ordinary type, consisting of left.-

hand and right-hand jambs, cross head, sill, and stiles, with the stile grooves somewhat modified as will be described. The lower sash 2 is mounted upon the left'hand lower rider 4 and. its counterpart 4' the right-hand lower rider, by means of the pivots 12 and 12' and the pivot bearings 13 and 13, and is held in the plane of sliding by the spring bolts 14 and 14 engaging with the slots 10 and 10. Similarly, the upper sash 3 is mounted upon the left-hand upper rider 5 and its counterpart 5 the right-hand upper rider, by means of similar pivots and pivot bearings, and is held in its plane of sliding by the spring bolts 15 and 15 engaging with the slots 11 and 11. a

The pair of riders 4 and 4 a cross sectional view of which is shown in Figure 4 are here constructed of wood faced with the metal plates 21 and 21 provided with the slots 10 and 10, and pivots 12 and 12'. These riders are longitudinally grooved as is shown at 35 to take the guide plates 16 and 16 set into the sash guides 7 and 7 andextending thefull length of the stile grooves. These guide plates are provided with notches or teeth 33 and 33 with which the catch bolts 28 and 28' set into the grooves 34 and 34 and actuated by the spring assemblies v 29 and 36 and 29 and 36 respectively engage,

and thereby prevent any upward movement of the riders. When these arresting mechanisms are disengaged by the coactions of the rides and sash through the agencies of the catch pins 9 and 9 working in the slots 8 and 8', the ridersslid in the stile grooves of the I window frame, being retained therein by the guide plates 16 and 16 and the parting beads 6 and 6. These riders are rabbeted throughout their lengths to receive the sashes, which are rabbeted inversely or complementarily as is shown in Figure 2 and in Figure 3.

Similarly, the pair of riders 5 and 5 a cross sectional view of which is "shown in Figure 4 are here constructed of wood faced with metal plates provided with slots and pivots,

are longitudinally grooved to takethe guide plates 17 and 17 mounted upon and screwed to the parting heads 6 and 6' extending the full length if the stile grooves, and are provided with catch bolts actuated by spring assemblies toengage with the notches or teeth of the guide plates to prevent any upward movement of the riders. When these arrestmg mechanisms are disengaged by the coactions of the riders and sash through the agencies of the catch pins working in their slots, the riders slide in the stile grooves of the window frame, being retained therein by the guide plates 17 and 17 and the external sash guides 20 and 20. These riders too are rabbeted throughout their, lengths to receive the sashes which are rabbeted inversely or complementarily as is shown in Figure 2. The riders 5 and 5' are considerably thicker will disclose.

The lower sash 3, somewhat narrower than is the standard sash supplied with the window frame but not otherwise different, is just sufliciently wide to fit snugly between its riders 4 and 4. It is rabbeted longitudinally along therear edges of the sides and bears on its sides at the lower edges the two pivot hearing plates 32 and 32'. The pivot bearings are continued into slots 30 and 30' to take the flatted pivots 12 and 12 at an angle somewhat less than ninety degrees. The pivot bearing plates and the rabbets are given the rounded off shapes illustrated at 31 of Figure 3 to permit the rotation of-the sash upon its pivots. The two spring bolts 14 and 14 with the glass 26, the glass retaining strip 25, and one part of the window catch 18, complete the lower sash ensemble,

The upper sash 4, somewhat narrower than is the lower sash, and of course considerably narrower than is the standard sash supplied with the window frame, but not otherwise different, is just sufficiently wide to fit snugly between its riders 5 and 5. This sash, rabbeted longitudinallyalong the rear edges of It is obvious that the lower and upper sashes of this improvement in window. construction can be made from the sashes supplied with the ordinary type of window frame by a few simple alterations.

The guide plates 16, 16 17, and 17 serve alsoas weather stripping and when used in the common double check rail window render it substantially air tight.

The operation of the invention is as 01- I lows: upon the release of the spring bolts 14 and 14' of the lower sash 2, the lower sash can be rotated about its pivots, allowing in its initial slight angular displacement the catch bolts 28 and 28' to engage in the notches or teeth 33 and 33' of the guide plates 16 and 16, thus locking the riders in their stile grooves and arresting any tendency to movement of the riders 4'and 4 caused by the pull on the riders of the partially unbalanced window weights. The sash can be rotated about its pivots to the angle 01f detachment and it can then be com letely removed from its riders, or it can e rotated until it makes weave? contact with the sill While still hanging from its riders, and in such position permits the outside face of the Window glass to be cleaned. Similarly, the upper sash can be rotated upon its pivots and detached from its riders or it can berotated until it makes contact either with the hanging lower: sash, or, if the lower sash has been detached, with the sill, and in such position permits the outside face of the window glass to be cleaned. Reversal of the order-of these operations serves to reassemble the sashes in the Window frame.

While the present embodiment of the invention has been described in detail, both as to materials and as to construction, the protection of all possible modifications of ma terials and of construction Within the spirit and scope of the invention as defined in the appended claims is sought. Thus, the invention is applicahie to sashes and to riders made Wholly or in part of Wood or of metal. And the arresting mechanisms may take any form consonant With their function oi look ing the riders in their stile grooves through the coaction of the sashes and riders.

Having described my invention and its operation, I claim:
